发布到 Shanghai Greeters: Volunteer tour guides in Shanghai

Hi, did a quick scan whether this question has already been asked, did not see that, if there is one, please point me to that direction.

Question - with an indian passport can i do transit into shanghai, if my stay is less than 24 hours? from internet forums believe that is done, however, have not been able to get into official website, so wanted to ask questions in this group about their experience.

Thanks in advance
